Hello everybody I have a 16 sierra stock battery and amp. I currently bought 4 8in sundown subs and will connect them to a 1200.1 Rockford Fostgate. Eventually on planning on upgrading to a 2500 amp, and I’m running a second amp for my door speakers. My question is what should I upgrade first,my alt or battery and which one?
